Analysis of Lhca content in PSI-LHCI of WT and ΔLhca1–4
plants. SDS-PAGE of PSI-LHCI purified from WT and ΔLhca1–4
plants, and PSI core. The region of the gel where Lhca1–4 and PsaD
migrate is shown. The identity of the bands from top to
bottom are: Lhca1, Lhca2, Lhca3, PsaD, and Lhca4. Note that one of
the two isoforms of PsaD appears as a faint band at the level of Lhca4.
